Scientists Gather in Denver for the 2011 PMM Science Team Meeting

Over 150 scientists from 10 different countries are meeting in Denver, Colorado, to discuss rain and snow and how to measure them from space. Only once a year members of the Precipitation Measurement Missions (PMM) Science Team come together to discuss the science surrounding both the current Tropical Rainfall Measuring Mission (TRMM) and the upcoming Global Precipitation Measurement (GPM) mission that will launch in 2014.

GPM Takes a Spin on the Centrifuge

Set to measure rainfall worldwide after launch in 2014, GPM's two solar panels are the latest components currently undergoing rigorous testing before being integrated with the spacecraft, a process that began seven months ago when the main structural elements went on an unusual ride.
